5.4 M10 switching outputs B1 and B2
The switching outputs are electrically isolated from each other and from the analog output.
Switching outputs B1 and B2 can be implemented electrically with two attachment types:
•
NAMUR switching output - Ri approx. 1kOhm
•
Low-resistance switching output with PNP technology
